Public health is actually the art and science of promoting health, prolonging life and preventing the diseases through informed choices and organized efforts of the communities, private and public, society, individuals and the organizations. It is highly concerned with the threats to health which are based on the population health analysis. Population in the question could be as large as inhabitants of various continents or as small as handful of people. The promotion of breastfeeding, hand washing, distribution of the condoms for controlling the risk of sexually transmitted diseases and delivery of vaccinations are just some common measures for the public health.
Objectives Of The Public Health ServicesPublic health intervention focuses on managing and preventing the injuries, diseases and other health related conditions. Several diseases are actually preventable through non-medical simple methods. For example, the research has proved that an act of washing hands with a good soap can easily prevent several contagious diseases. While in other cases, controlling a pathogen or treating a disease can be very important in preventing the spread to others, like during the outbreak of any infectious disease, or the contamination of water supplies or food. Vaccination programs and other communication programs of public health are common measures that are usually taken. Such measures have highly contributed to health of the masses and also increase in the life expectancy.
Public Health ProgramsMost governments recognize importance of the programs of public health in reducing the disability, incidence disease, various mental and physical health conditions and effects of aging, although generally the public health receives significantly less funding from government as compared with medicine. As it has now become clear that habit eventually develops into an addiction and may damage public health in general, many governments have taken up the issue of public health as a serious one. Public health programs in recent years have made great strides in the promotion of health by providing vaccinations, including eradication of the smallpox; a disease which has plagued the humanity for numerous years. The WHO (World Health Organization) identifies the core functions of the public health programs as:
- Engaging in the partnerships where the joint action is required and providing leadership on the matters that are critical to human health.
- Stimulating the generation and shaping the research agenda, dissemination and translation of the valuable knowledge.
- Setting the standards and norms and monitoring and promoting their implementation.
- Articulating the evidence-based and ethical policy options.
- Assessing the health trends and monitoring health situations.
- Document the impacts of intervention, or track the progress towards the specified goals.
- Serve as the early warning system to impend the public health emergencies.
- Monitor and clarify epidemiology of the health problems, allow the priorities to be all set, and inform the health policy.
- Diagnose, monitor, and investigate the health hazards and health problems of the community.
Applications In The HealthCarePublic health also contributes to the medical care by assessing and identifying the population needs for the health care services by:
- Assessing and evaluating the current services to check if they are meeting all the objectives of health care system.
- Identifying most appropriate interventions and increasing mental health awareness for good physical health .
- Ascertaining requirements as they are expressed by the health professionals, other stakeholders and the public.
- Assessing the cost-effectiveness and considering effects on resources for the proposed interventions.
- Supporting the decision making in planning health services and health care including any of the necessary changes.
- Educating, informing, and empowering the people regarding health issues.
